Yes. For a Chicago-based arts nonprofit, I’d prioritize firms that understand both mission-driven digital work and membership infrastructure—not just agencies that make attractive nonprofit websites.

My shortlist

1. Venture Industries Online — best arts-specific fit
   • This is the first firm I’d contact.
   • They explicitly specialize in websites for arts organizations and artists and have worked with organizations including the League of Chicago Theatres and performing-arts organizations. Their League of Chicago Theatres project involved multiple complex sites serving member theatres, patrons, artists and administrators. ventureindustriesonline.com
   • Particularly compelling if your portal needs to connect membership, events, ticketing, content, and different user groups.

2. Mightybytes — best mission-driven digital/product partner
   • Chicago-based and focused specifically on mission-driven organizations.
   • Stronger candidate if this is a true custom portal/application, rather than simply a member-login area attached to a website. Their work includes product development, front- and back-end development, integrations, QA, training, hosting and ongoing support.
   • I'd put them high on the list if accessibility, sustainability, UX, and long-term maintainability matter.

3. Adage Technologies — best for a substantial custom build
   • Chicago software/digital firm with capabilities spanning strategy, UX, custom development, integrations and ongoing support.
   • I'd consider them if you're envisioning sophisticated functionality—member dashboards, profiles, payments, event registration, CRM integration, personalized content, etc.—rather than a conventional WordPress membership site.

4. Promet Source — best for complex nonprofit/association requirements
   • Chicago-based and particularly strong in Drupal, accessibility, security and organizations with complicated content/governance requirements.
   • Worth approaching if your nonprofit has a sizable membership, multiple permission levels, extensive archives/resources, or significant integrations.

5. Dialogue Theory — best UX/design-led option
   • A Chicago digital design/development studio focused on mission-driven organizations.
   • I'd include them if the portal needs to feel exceptionally polished and arts-oriented, rather than like a generic association-management system.

6. click5 Interactive LLC — good boutique/custom-development option
   • Chicago-based and does both websites and web applications, including WordPress and more complex application development.
   • Could be a good fit if you want a smaller team and more direct access to the people actually building the system.

One important distinction

I'd first decide whether you actually need a custom membership portal or a membership-management platform integrated into a redesigned website.

For example, Chicago organizations already use fairly sophisticated member systems. The Chicago Cultural Alliance has a member portal where organizations can log in, submit events, and access member resources. www.chicagoculturalalliance.org Chicago Women in Philanthropy's system supports accounts, event registration, invoices, profiles, career resources and member-only communications. members.cwiponline.org

If your requirements are things like:

• member signup/renewal
• recurring dues
• member profiles/directory
• event registration
• member-only content
• invoices/receipts
• automated emails
• staff administration
• CRM integration

…I would not automatically commission someone to build all of that from scratch. I'd ask the agencies to recommend whether to use something like a membership/CRM platform underneath the portal.

If, however, you want something more distinctive—e.g. artist profiles, portfolios, member networking, private archives, calls for artists, grant/program applications, member benefits, community forums, or sophisticated permissions—then a custom development partner becomes much more attractive. Chicago's Bridge/Artists United project is an interesting local example of this more elaborate model: it combines membership tiers, a searchable creative-worker directory, profiles, archives, benefits and other member resources. www.bridge-chicago.org

Who I'd invite to the RFP

I'd start with four rather than sending an RFP to 15 firms:

Then add Dialogue Theory if visual/UX quality is a major priority.

One caveat: I would not choose purely on portfolio aesthetics. For a membership portal, the crucial questions are what CRM/membership systems they've integrated, how they handle authentication and permissions, recurring payments, data migration, accessibility, security, and post-launch support.

If you tell me roughly (1) number of members, (2) current website/CMS, (3) current CRM or membership database, (4) desired portal features, and (5) budget range, I can narrow this to 3 firms and give you a side-by-side recommendation, including which one I'd hire.

Yes. For a Chicago arts nonprofit, I’d focus less on generic web-design shops and more on firms that understand membership workflows, nonprofit CRMs/AMSs, events, payments, gated content, and accessibility.

Based on current research, these are the firms I’d put on the first outreach list:

My shortlist

1. Mightybytes — strongest overall fit

• Chicago-based, mission-driven digital agency.
• Does product/web development, UX, accessibility, integrations, training, hosting, and ongoing support.
• Particularly attractive if the portal needs to be a real digital product rather than simply a members-only section of your website. Aero Design
• I'd definitely include them in an RFP.
• Dialogue Theory — best for UX + complex nonprofit experience

• Chicago studio focused on mission-driven organizations and complex digital experiences.
• Good candidate if the portal needs a sophisticated, contemporary arts/cultural experience rather than an off-the-shelf association site.
• Neoteric Design — best for custom technology

• Chicago digital product/software firm with an emphasis on usable, maintainable web applications.
• Particularly interesting because its past work includes arts/education nonprofit web projects.
• I'd consider them if you envision custom functionality, integrations, or a portal that may evolve substantially over time.
• 83/Creative — best specialist for membership portals

• This is one of the most directly relevant firms I found: they explicitly build member portals and web applications for nonprofits and associations, including CRM/AMS integrations, WordPress/Drupal development, UX, and content strategy. 83 Creative
• They advertise 20+ years of experience and 100+ projects.
• Even though they're not Chicago-based, I'd invite them to bid. For this particular project, specialization matters more than geography.
• EDUCO Web Design — good nonprofit + Drupal/WordPress option

• Chicago-area agency with 20+ years in nonprofit web design and experience with organizations including LISC Chicago, Chicago Loop Alliance, Women Employed and BUILD Chicago. Educo Web Design
• Worth considering if the portal will live alongside a substantial public-facing website.
• View Marketing & Creative — interesting arts/nonprofit design option

• Their Chicago nonprofit work specifically discusses membership portals, member directories, events and integrations, with an emphasis on making the portal feel visually continuous with the public website. View Marketing
• I'd put them on the list if brand/design and member experience are especially important.

Two more I'd investigate

• Thirdwave — Chicago web-development firm with experience across nonprofit and institutional organizations; potentially a good fit for a technically substantial portal.
• Cybernautic Web Design — Chicago agency that specifically describes building password-protected customer/employee portals with multi-user accounts and access levels.

One important alternative: don't necessarily build a portal from scratch

If by "membership portal" you mean something like:

Member logs in → sees profile → renews membership → pays dues → registers for events → accesses member-only content → updates preferences → receives communications

…I would first determine whether you actually need custom software.

There are specialized membership/association-management platforms that can provide much of this functionality, with the agency handling the website, UX, integrations and implementation. For example, JourneyCARE is specifically positioned as an all-in-one system for membership organizations, including website/CRM, communications, payments, automations, member portals, events and learning.

That's potentially much less risky for a nonprofit than commissioning an entirely custom membership database.

If this were my RFP

I'd probably invite 5 firms:

I'd then give all five the same requirements document and compare proposals on architecture, integration strategy, accessibility, staff usability, ongoing costs, and ownership—not just visual design.

A particularly important question for an arts nonprofit is what system currently owns your member data. If you're using something like Salesforce, Tessitura, PatronManager, Neon One, Bloomerang, Blackbaud, Fonteva, Personify, WildApricot, etc., the best agency may be the one with deep experience integrating that particular system.

If you tell me (1) your approximate budget, (2) current website/CMS, (3) current CRM or membership database, and (4) what you want members to be able to do inside the portal, I can narrow this to 3–5 firms that are genuinely well matched, including likely project-cost ranges and specific relevant case studies.

• Sandstorm Design - 4422 N Ravenswood Ave #50, Chicago, IL 60640, United States
• Maven Digital - 23 N Racine Ave, Chicago, IL 60607, United States
• Progressive Data Services - 2161 W Leland Ave, Chicago, IL 60625
• NAV & Associates - 1018 W Madison St Ste 9, Chicago, IL 60607, United States
• Big Buzz Idea Group - 4055 W Peterson Ave #105, Chicago, IL 60646, United States
• Heller Consulting - 53 W Jackson Blvd, Ste 622, Chicago, IL 60604
• Chicago Association Management - 400 E Randolph St Apt 3115, Chicago, IL 60601, United States
• Smithbucklin - 330 N Wabash Ave #2000, Chicago, IL 60611, United States
• GiveCentral - 2 North Riverside Plz, Ste 1350, Chicago, IL 60606
• Access Direct Nonprofit Marketing - 209 Des Plaines Ave, Forest Park, IL 60130, United States
• Technical Registration Experts, Inc. - 1932 S Halsted St #413, Chicago, IL 60608, United States
• Nonprofit Megaphone - 1230 W 34th St, Chicago, IL 60608, United States
• Beth Interactive Inc. - 4541 N Ravenswood Ave #303, Chicago, IL 60640, United States

Yes. For a Chicago-based arts nonprofit, I’d put together a shortlist that balances three things: membership/portal engineering, nonprofit experience, and sensitivity to arts/cultural audiences. I would not hire a general branding agency unless it can demonstrate that it has actually built authenticated member experiences.

My shortlist

1. Sandstorm Design — strongest Chicago agency to interview

Sandstorm is probably my first call if you want a polished, audience-centered experience rather than simply bolting a login onto your existing website. It is Chicago-based and has substantial Drupal/WordPress, UX research, accessibility, and nonprofit experience. Its portfolio includes nonprofit and association work, and Pantheon describes 15+ years of Drupal/WordPress development. Pantheon Directory Clutch

Best for: a sophisticated member portal + website redesign, especially if your audience experience and brand are important.

2. 83/Creative — strongest specialist for the actual membership problem

This is the one I'd make sure is in your RFP. Their stated specialty is membership organizations, and their services explicitly include member portals, web applications, CRM/AMS integrations, WordPress and Drupal. That's unusually close to your requirement. 83 Creative

Best for: a portal that involves member accounts, directories, renewals, permissions, events, integrations, etc.

3. Maven Digital — particularly interesting for an arts/mission-driven organization

Maven Digital is a Chicago digital product consultancy with a social-impact orientation and clients including the Chicago Community Trust, Boys & Girls Clubs of Chicago, Shedd Aquarium, Oxfam International and the University of Chicago.

Best for: a more strategic/custom digital product where the portal is part of a broader transformation of how members interact with the organization.

4. Eastern Standard — excellent nonprofit digital/UX option

Eastern Standard specializes in nonprofit digital experiences and works across UX research, design, WordPress, Drupal, analytics and integrations. They specifically discuss integrations with systems such as DonorPerfect, Donorbox, Classy and Blackbaud. Eastern Standard

Best for: an organization that needs the portal integrated into a broader fundraising, content and digital strategy.

5. Kanopi Studios — technical heavyweight worth including

Kanopi has substantial nonprofit experience in both WordPress and Drupal. Its nonprofit portfolio includes organizations such as PEN America and Humane World for Animals; it also cites a multisite solution supporting 150+ member sites. Kanopi Studios

Best for: a technically complex or high-traffic portal where scalability, CMS architecture and long-term maintenance matter.

6. View Marketing & Creative — especially worth considering because of the arts/nonprofit fit

Their Chicago work for Chicago Women in Philanthropy is particularly relevant: they describe styling a membership portal to match the organization's Webflow site, creating a seamless transition between the public website and member dashboard. View Marketing

Best for: a visually distinctive arts organization where the portal needs to feel like an extension of the brand rather than an ugly third-party application.

7. iTech4Web — technical/value-oriented option

Progressive Data Services is another local option if the project is more database/CRM-oriented, while iTech4Web specifically advertises Chicago-area Drupal/WordPress development and nonprofit work. iTech4Web

Best for: a technically focused build where budget and CMS expertise are more important than a big creative-agency experience.

If it were my RFP

I'd invite four firms rather than sending it to 10:

I'd use Eastern Standard or Kanopi as alternates if the portal is technically complex.

One important point: don't frame the RFP as "we need a new website with a membership section." If this is a real membership portal, ask agencies to architect the member system first—identity/authentication, membership tiers, renewals, payments, permissions, profiles, directories, event access, content access, CRM synchronization, reporting and accessibility—and then design the public website around it.

For an arts nonprofit, I'd also ask each firm to demonstrate one comparable authenticated/member experience, not just show you beautiful nonprofit websites. A gorgeous homepage is weak evidence that an agency can build a reliable membership system.

If you tell me (1) approximate membership count, (2) what members need to do inside the portal, (3) your current website/CMS, and (4) rough budget, I can narrow this to 2–3 firms and tell you exactly why I'd choose each one.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic “website redesign.” A membership portal usually touches CRM/data, payments, events, permissions, member communications, and the public-facing brand experience. Chicago organizations are already tackling it this way—for example, Chicago Loop Alliance’s RFP called for a combined website + CRM/association-management system with member portal, billing, events, donations, listings, and migration. loopchicago.com

My shortlist

1. Dialogue Theory — strongest agency-style candidate
Chicago-based digital design/development studio working with nonprofits and mission-driven organizations. I'd put them near the top if you want a beautiful, custom member experience rather than simply configuring an association-management platform.

2. Heller Consulting — strongest technology/CRM candidate
Particularly compelling if the portal needs to sit on top of Salesforce or another sophisticated nonprofit CRM, or if data migration/integration is a major concern. Their focus is nonprofit technology strategy, implementation, data, and organizational adoption.

3. NEW Marketing Solutions — strongest arts/culture specialist
This one is especially worth approaching because they're Chicago-based and specifically focused on arts and culture organizations, with experience around ticketing/Tessitura and digital strategy.

4. Lipman-Hearne — strong membership + nonprofit communications option
A good candidate if membership growth, fundraising, brand, communications, and the digital experience all need to be addressed together. Their positioning explicitly includes membership organizations and nonprofit/philanthropic work.

5. Smithbucklin — best if you need more than development
This is much larger than a typical web agency. They provide membership growth/engagement, marketing, technology and broader association-management capabilities. I'd consider them if your nonprofit wants a long-term operating partner, not merely someone to build the portal.

6. Chicago Association Management — worth considering for membership operations
More of an association-management partner than a pure software-development agency. Their services encompass membership, communications, website/digital work and operational support.

One non-Chicago firm I'd add

Sage70 is particularly interesting for an arts nonprofit. It's a nonprofit technology/data strategy consultancy whose stated sectors include Arts, Culture & Humanities, and it lists the Art Institute of Chicago among its client success stories. www.sage70.comwww.softr.io

Sage70

Also: don't assume you need a custom-built portal

Depending on what you mean by “membership portal,” you may get a better result by having an agency select and configure an existing platform rather than building everything from scratch.

For example, Cuseum is specifically built around cultural organizations and offers branded member portals, digital membership cards, member lifecycle tools and integrations with systems including Tessitura, Altru, Salesforce, Blackbaud, Neon CRM, Eventbrite and others. cuseum.com

Cuseum

And Softr has specifically positioned its platform for arts organizations, including member portals, CRM functionality, secure logins and integrations. www.softr.io

If I were running the RFP

I'd invite 4 firms to pitch:

Then I'd potentially add Cuseum as a platform alternative so you can compare “custom agency build” against “configure a purpose-built cultural membership platform.”

The key questions I'd put in the RFP are: What CRM should sit underneath this? How will payments and renewals work? Can members manage their own profiles? How will events/ticketing integrate? What happens to our existing member data? What staff/admin tools do we get? What will we own after launch? And what is the 3-year total cost—not just the initial build?

If you tell me (1) roughly how many members you have, (2) your current CRM/ticketing system, (3) what you want members to be able to do in the portal, and (4) a rough budget, I can narrow this to 3–5 firms and give you a much more opinionated recommendation, including which ones I would not bother contacting.

Yes. For a Chicago arts nonprofit, I’d prioritize firms that understand both mission-driven digital experiences and the underlying complexity of membership—accounts, dues, renewals, events, member directories, gated content, CRM integration, and payments.

My shortlist

1. Sandstorm Design — strongest overall fit
   • Chicago-based and focused on mission-driven organizations.
   • Particularly strong in UX, accessibility, Drupal/WordPress, and larger data-driven web platforms.
   • I’d put them near the top if the portal needs to be a polished, custom experience rather than simply configuring membership software. clutch.co

2. Adage Technologies — best for complex integrations
   • Chicago firm with substantial custom web/application-development capability.
   • Particularly interesting if the portal needs to connect a membership database/CRM, ecommerce, events, payments, or other existing systems.
   • They have nonprofit experience involving self-service account portals and ecommerce. clutch.co

3. Dialogue Theory — best for a sophisticated arts/cultural experience
   • Chicago digital design/development studio working with mission-driven organizations.
   • I'd consider them if brand, UX, storytelling and member experience are as important as the underlying technology.

4. click5 Interactive LLC — good mid-sized Chicago option
   • Does both web design and application development, including WordPress and web applications.
   • Worth talking to if you want a relatively hands-on team rather than a large enterprise agency.

5. TXI — for a genuinely custom product
   • Chicago-headquartered digital product consultancy specializing in custom software and experience-led products.
   • I'd consider them if you're envisioning something more ambitious than a conventional website/member portal—for example, a sophisticated digital community or bespoke member application. clutch.co

Two alternatives I'd investigate

Aluent Group is particularly interesting because it has an unusually direct membership-portal precedent: it helped implement the complex online membership system for The Morton Arboretum, including membership packages, multiple individuals, renewals, discounts and ecommerce integration. That's very close to the problem you're describing. aluent.com

View Marketing & Creative is worth a conversation if your priority is a beautiful, manageable nonprofit website with a membership portal integrated into the experience. It specifically describes building membership portals alongside a Webflow nonprofit site. www.view-marketing.com

One important distinction

I'd first decide whether you actually need an agency to build a portal from scratch.

If your requirements are things like:

• member login/profile
• membership levels
• dues and recurring payments
• renewals
• event registration
• member directory
• gated resources
• email integration
• basic CRM synchronization

...you may get a better result by having an agency select/configure/integrate an existing membership platform rather than commissioning custom software.

For example, Chicago-based Covey is specifically developing membership software for nonprofits and associations with member-only pages, document libraries, profiles, events, payments and migrations—but it is currently in private beta, so I wouldn't make it the primary solution for an imminent project. coveyhq.com

Who I'd invite to the first round

If I were running the RFP, I'd probably invite Sandstorm, Adage, Dialogue Theory, Aluent, and one smaller shop such as click5. That gives you five meaningfully different approaches rather than five interchangeable web-design agencies.

And I would make the RFP ask each firm to show 2–3 actual membership/portal projects, identify the underlying platform/CRM, explain what was custom-built versus configured, and provide a rough total cost of ownership for 3 years, not just the initial build price.

If you tell me roughly your membership size, annual budget, existing website/CRM (e.g. WordPress, Salesforce, Tessitura, Spektrix, PatronManager, etc.), and what you want members to do inside the portal, I can narrow this to 3–5 firms and compare their likely fit, project cost, and relevant arts/nonprofit experience.

For a Chicago arts nonprofit, I’d look for a firm that understands membership economics, cultural audiences, donations/ticketing/events, accessibility, and integrations—not just a general web designer. A membership portal usually touches CRM, payments, content permissions, events, email, and data migration.

Here are firms I’d put on your shortlist:

Strong fits for a custom membership portal / digital platform

Mightybytes

A good candidate if you want a mission-driven digital partner rather than a purely technical shop. They focus on purpose-driven organizations and handle digital product strategy, development, accessibility, and ongoing support.

Ask them about:

• member dashboards
• integrations with your CRM/ticketing/donation systems
• accessibility (WCAG)
• long-term maintenance model

LaunchPad Lab

Worth approaching if you need a more custom application rather than a templated membership site. They explicitly work with nonprofits and social-impact organizations on custom digital tools. launchpadlab.com

Best fit if you need:

• custom member workflows
• complex permissions
• integrations with internal systems
• a portal that could evolve into a broader platform

Promet Source

A strong option for larger nonprofits that need robust CMS and open-source solutions (especially Drupal). They have experience with complex, multi-stakeholder digital platforms.

Best fit if you have:

• many member types
• institutional partners
• extensive content libraries
• governance requirements

Strong arts/nonprofit design + membership experience

LimeRed Studio

A mission-oriented Chicago studio with experience in branding, UX, websites, accessibility, and integrations. They may be a good fit if the portal needs to feel highly aligned with your artistic identity.

Best fit if you care about:

• beautiful member experience
• storytelling
• audience engagement
• balancing design with functionality

Dialogue Theory

A smaller, high-touch digital studio that focuses on UX, design, and development for mission-driven organizations.

Best fit if you want:

• close collaboration
• a thoughtful UX process
• a boutique partner

If you may not need a fully custom build

Before commissioning custom software, I’d also evaluate whether a strong membership platform plus a custom front end would solve your needs. Chicago nonprofits and associations often use combinations of CRM + membership tools + websites rather than building everything from scratch. For example, Chicago organizations have pursued systems combining websites, CRM, association management, events, payments, and member portals. loopchicago.com

Possible approaches:

• Website + membership platform integration (lower cost, faster)
• CRM/association management system customization
• Fully custom portal (highest flexibility, highest cost)

My suggested first outreach list (5 firms)

If I were issuing an RFP, I’d invite:

1. Mightybytes — mission alignment + digital product experience
2. LaunchPad Lab — custom portal capability
3. LimeRed Studio — arts/culture-friendly UX and design
4. Dialogue Theory — boutique collaboration
5. Promet Source — enterprise-grade CMS/platform work

I’d also consider a specialized membership/association technology consultant if your portal is primarily about renewals, member tiers, benefits, directories, events, and communications rather than a unique software product. Chicago has firms such as NAV & Associates that focus on membership operations and digital engagement strategy.

For an arts nonprofit, I’d include in your RFP:

• number of members and membership tiers
• whether members need profiles/directories
• event/ticketing integration needs
• donation integration
• restricted content/library needs
• accessibility requirements
• current CRM (e.g., Salesforce, Blackbaud, Neon, Bloomerang, Tessitura, etc.)
• budget range and desired launch date

That information will dramatically change which firms are the best fit.

Yes. For a Chicago-based arts nonprofit, I’d approach a fairly targeted shortlist rather than a generic web-design shop. A membership portal usually involves some combination of authentication, member profiles, dues/payments, event registration, gated content, CRM integration, permissions, and staff administration—so you want proven membership + nonprofit + digital product experience.

My shortlist

1. Adage Technologies — Best for a substantial custom portal
   • Chicago-based and technically strong in custom web applications and integrations.
   • Particularly interesting if the portal needs sophisticated account management, payments, databases, or integrations rather than simply styling an existing membership platform.
   • Clutch currently lists Adage at 5.0 and specifically notes its experience in the arts and nonprofit sectors. clutch.co
   • Ask them: Can you show us a comparable member portal, not just a nonprofit website?

2. Dialogue Theory — Best for UX + mission-driven digital experience
   • Chicago studio focused on digital strategy, UX/UI and web development for mission-driven organizations.
   • I'd put them high on the list if the portal needs to be genuinely pleasant for artists, members, donors, staff, etc., rather than merely functional.
   • Their work is explicitly oriented toward complex nonprofit/civic digital experiences.

3. Sandstorm Design — Best for a larger, more complex organization
   • Chicago-based, UX-driven agency with experience in enterprise web development, accessibility and data-driven applications.
   • Particularly worth considering if your nonprofit has a sizable existing website/CRM ecosystem or expects the portal to become a significant digital platform.
   • They work extensively with Drupal/WordPress and emphasize inclusive design.

4. click5 Interactive LLC — Good middle-market custom-development option
   • Chicago-based "creative technologists" doing both WordPress and web-application development.
   • Worth talking to if you need something more customized than a conventional nonprofit website but don't want an enormous enterprise engagement.

5. Bark Design — Especially interesting for arts/culture
   • This is one I'd put on the list specifically because Bark says it works with museums, education, technology, the arts and healthcare, in addition to mission-driven organizations.
   • It combines visual/brand work with UX, CMS, intranet and web development, which could be useful if the member experience needs to feel highly tailored to your arts organization.

6. LimeRed Studio, Inc. — Good mission/brand/UX choice
   • Chicago agency focused on purpose-driven organizations, with a strong nonprofit orientation.
   • I'd consider them if the portal is part of a broader digital/brand redesign rather than a standalone software project.

One firm I'd definitely interview: Orbit Media

Orbit Media Studios is particularly compelling for an arts nonprofit. They have a dedicated nonprofit practice and publicly cite work with Goodman Theatre, the Greater Chicago Food Depository, Erikson Institute and other nonprofits. Their Goodman Theatre case study reports a 55% increase in conversions. www.orbitmedia.com

They also explicitly discuss integrating websites with CRMs, databases and third-party systems rather than treating the website as an isolated marketing property. www.orbitmedia.com

Caveat: I'd want Orbit to demonstrate that they can own the portal/application portion of your project—not just the public-facing website.

An intriguing specialist option: View Marketing & Creative

View has a particularly relevant Chicago nonprofit case study: Chicago Women in Philanthropy. They redesigned the site's UX while integrating its existing membership software, including making the member experience visually cohesive with the main site. They specifically discuss integrations with MemberClicks, WildApricot, YourMembership and similar platforms. www.view-marketing.com

That's potentially a much better model if your organization doesn't actually need custom membership software and instead needs a beautifully designed front end around an existing membership system.

How I'd narrow it down

I'd issue an RFP/interview with 5 firms, probably:

Then add View if you're considering an existing membership platform rather than building the portal from scratch.

One important distinction: don't ask agencies simply for "a membership portal." Give them a list of required member journeys—e.g. join → pay dues → create profile → access member-only content → register for event → renew → update payment → staff manages membership—and ask each firm to propose the architecture. That will quickly reveal who actually understands the problem.

If you tell me your approximate budget (e.g. $50k, $100k, $250k+), number of members, existing CRM/membership software, and what the portal needs to do, I can narrow this to 3 firms I'd actually invite to bid, including likely project fit and questions to ask each.

Yes. For a Chicago-based arts nonprofit, I’d build the shortlist around firms that have demonstrated experience in arts/culture + nonprofit work + membership/portal functionality, rather than hiring a generic web-design shop.

My shortlist

1. Venture Industries Online — strongest arts-sector fit
   • This would be one of my first calls.
   • They specifically build websites for arts organizations and artists, and their portfolio includes the League of Chicago Theatres. That project involved multiple complex sites serving member theatres, patrons, artists, and administrators. ventureindustriesonline.com
   • Particularly attractive if your portal needs to feel arts-specific and beautifully designed, rather than like a generic association-management system.
   • Venture Industries Online

2. Sandstorm Design — best for a sophisticated UX/platform
   • Chicago-based, women-led agency with a strong emphasis on UX, inclusive design, and enterprise web development for mission-driven organizations.
   • I'd put them high on the list if the portal involves complicated member journeys, multiple audiences, integrations, accessibility requirements, or a substantial redesign alongside the portal.
   • Sandstorm Design

3. Orbit Media Studios — excellent nonprofit + membership experience
   • Orbit has substantial Chicago nonprofit experience. Its work for Awakenings, a Chicago arts/healing nonprofit, included strategy, UX, design, development, accessibility, events, and conversion journeys. www.orbitmedia.com
   • More importantly for you, Orbit also built the site for The Executives' Club of Chicago, with explicit goals around attracting members, showcasing events, and serving existing members. www.orbitmedia.com
   • That's a particularly relevant combination of nonprofit + membership + events + Chicago.
   • Orbit Media Studios

4. View Marketing & Creative — particularly strong if you're integrating existing membership software
   • Their Chicago Women in Philanthropy project is unusually relevant: the organization already had membership software, and View redesigned the public site and coordinated the membership-software experience so the portal felt like one cohesive website. www.view-marketing.com
   • They specifically discuss integrations with MemberClicks, WildApricot, YourMembership, etc.
   • I'd move them toward the top if you already have a membership database/platform and don't necessarily want to replace it.
   • View Marketing & Creative

5. Design In Chicago — good candidate for a genuinely custom portal
   • Their capabilities specifically include portal/dashboard development, intranet portals, CRM integration, LMS development, web applications, and custom digital products.
   • I'd investigate them if by "membership portal" you mean more than gated content—for example, member profiles, directories, applications, payments, dashboards, resources, events, or custom workflows.
   • Design In Chicago

6. Mightybytes — strong mission-driven/strategy option
   • Chicago-based and deeply experienced with nonprofits. Their work with Chicago Community Trust included digital strategy, accessibility, website work, and improving the user experience of a major registration system. ventureindustriesonline.comwww.mightybytes.comwww.tecture.com
   • I'd consider them particularly if the portal is part of a larger digital transformation, rather than simply a website build.
   • Mightybytes

One wildcard I'd interview

Tecture is worth considering if the portal is really a custom software application rather than a website with member login. They're Chicago-based and explicitly develop custom web applications for nonprofits, including WordPress integrations and custom software. www.tecture.com

Tecture

How I'd narrow it

I'd probably issue an RFP to 4 firms:

Then add Design In Chicago or Tecture if you anticipate substantial custom application development.

The biggest question before selecting an agency is what you mean by "membership portal." A portal with login + gated resources is a very different project from one with membership applications + dues + profiles + directory + events + ticketing + CRM integration + personalized dashboards.

If you give me (1) your approximate budget, (2) number/type of members, (3) what the portal needs to do, and (4) what system you currently use for CRM/membership/ticketing, I can turn this into a ranked 5–7 firm shortlist with estimated project-fit, likely budget tier, relevant case studies, and who I'd contact first.

For a Chicago-based arts nonprofit, I’d look beyond generic web shops and prioritize agencies that understand membership ecosystems: CRM integration, dues/subscriptions, events, ticketing, donor/member journeys, accessibility, and arts-sector audiences. A good shortlist to approach:

How I’d narrow the list

For an arts nonprofit, I’d probably invite 4 firms to an RFP/discovery conversation:

1. Venture Industries Online — if your priority is arts-sector understanding. ventureindustriesonline.com
2. Adage Technologies — if the portal will involve serious integrations (CRM, ticketing, databases, permissions). clutch.co
3. Orbit Media Studios — if you need strong nonprofit UX, storytelling, accessibility, and maintainability. www.orbitmedia.comwww.orbitmedia.com
4. Sandstorm Design or Spry Digital — if you expect a larger custom platform build. clutch.co

Questions I’d ask every agency

• Have you built member portals, not just nonprofit websites?
• Which membership/CRM platforms have you integrated with? (e.g., Salesforce, Neon One, Blackbaud, Fonteva, MemberClicks, WordPress membership tools)
• Can members:
  • renew dues?
  • update profiles?
  • access benefits/resources?
  • register for events?
  • receive segmented communications?
• How will you handle accessibility (WCAG), especially for arts audiences?
• Who owns the code, hosting, and integrations after launch?
• What ongoing support model do you offer?

A rough budget expectation: a serious custom membership portal for a nonprofit often lands anywhere from $40k–$150k+, depending on integrations, design complexity, data migration, and whether it is a portal layered onto an existing website or a full platform rebuild.

If you share your membership size, current website/CMS, CRM or ticketing system, and desired portal features, I can help narrow this to the 3–5 firms most likely to fit.

Yes. For a Chicago-based arts nonprofit, I’d prioritize firms that can handle more than a marketing website: member accounts, payments/renewals, events, directories, permissions, CRM/AMS integrations, and a staff-admin experience.

My shortlist

1. Adage Technologies — strongest candidate for a complex portal
   • Chicago-based and experienced with custom software and digital platforms.
   • Particularly interesting if you need a genuinely custom member portal rather than simply styling an off-the-shelf membership system.
   • They have experience with self-service account portals and nonprofit digital projects.
   • Best for: sophisticated integrations, custom workflows, CRM/ERP connectivity, larger-scale builds.

2. Thirdwave — excellent for complex nonprofit/member ecosystems
   • Chicago web-development firm with full-stack capabilities.
   • Their work includes consolidating multiple systems into a portal environment, with migration, training, calendars and custom applications.
   • Best for: an organization whose membership portal needs to connect to several existing systems. loopchicago.com

3. Sandstorm Design — strong UX/accessibility choice
   • Chicago agency with substantial experience in mission-driven organizations, UX, accessibility and enterprise web development.
   • A good fit if the portal needs to serve a diverse arts audience and you care deeply about usability and accessibility.
   • Best for: member experience + accessible design + robust CMS.

4. Dialogue Theory — worth interviewing for a highly user-centered portal
   • Chicago digital design/development studio focused on mission-driven organizations and complex digital experiences.
   • I'd put them on the list if the project involves significant discovery, UX research, or rethinking how members interact with the organization.
   • Best for: designing a great member experience rather than simply implementing software.

5. Design In Chicago — interesting mid-sized option
   • Their capabilities specifically include portal/dashboard development, intranet portals, CRM integration and web applications, alongside conventional web design.
   • Best for: a portal that needs custom functionality but doesn't necessarily require a huge enterprise implementation.

6. Mightybytes — particularly good mission fit
   • Chicago-based and focused on mission-driven organizations, with web/product development, accessibility, training and ongoing support.
   • I'd seriously consider them if sustainability, accessibility and nonprofit culture are important selection criteria.
   • Best for: mission alignment + thoughtful digital product development.

One more option if your membership system is the real problem

Heller Consulting is worth considering as a technology/CRM strategy partner, particularly if you're unsure what your underlying membership/CRM architecture should be. They specialize in nonprofit technology, CRM implementations, data migration and organizational adoption.

That distinction matters. Don't hire a web-design agency first if the real project is replacing an association-management system. A good firm should help you decide whether to build a portal around something like Salesforce, a dedicated AMS, WordPress/Drupal, or a custom application.

I'd approach these four first

If I were running your RFP, my initial outreach would be:

There is also a useful Chicago precedent: the Chicago Loop Alliance's recent website/CRM RFP explicitly called for integrating a member portal, billing/payments, event registration, member listings, applications, fundraising and CRM/association-management systems. That is very close to the architecture I'd expect an arts nonprofit to need. loopchicago.com

And Chicago arts organizations are already using fairly sophisticated membership experiences—for example, the Chicago Cultural Alliance has a member portal with authenticated accounts and member resources, while Chicago Women in Philanthropy combines accounts, events, invoices, profiles, a directory and members-only benefits. www.chicagoculturalalliance.org

My recommendation: don't ask these firms simply for a "membership website." Ask for a member-experience and technology architecture engagement, followed by implementation. That framing will produce much better proposals.

If you tell me roughly (a) number of members, (b) current CRM/membership software, (c) what members need to do inside the portal, and (d) your approximate budget, I can narrow this to 3 firms and give you a suggested RFP/brief and questions to use in the agency interviews.

Yes. For a Chicago arts nonprofit, I’d avoid treating this as a generic website project. A good membership portal usually involves member accounts, dues/renewals, event registration, gated content, CRM integration, email automation, payments, and staff administration—so you want a firm that understands both arts audiences and the underlying technology.

I’d put these firms on your initial shortlist:

1. Adage Technologies — strongest for a complex/custom portal

Adage Technologies
Web
Address: 10 S Riverside Plaza Ste 1500, Chicago, IL 60606, United States
Phone: +1 312-258-1200
Adage is probably my first call if the portal is more than a relatively simple member login. They combine strategy, UX, and custom software development and have experience with associations and cultural institutions. Their portfolio includes work for the American Academy of Pediatrics and The Met, including sophisticated account/e-commerce experiences. adagetech.com

Adage Technologies

Best for: custom member dashboards, integrations, complex databases/CRM, unusual workflows, scalability.

2. Dialogue Theory — strong UX + mission-driven fit

Dialogue Theory
Web
Address: 1932 S Halsted St #509, Chicago, IL 60608, United States
Phone: +1 617-922-3790
This Chicago studio focuses on digital strategy, UX/UI, and development for mission-driven organizations. I'd consider them particularly if the member experience itself is the priority rather than simply getting an existing membership system connected to your website.

Best for: an elegant, highly usable portal; organizations that need discovery/research and custom UX.

3. IDE Interactive, Inc. — strong custom-product option

IDE Interactive, Inc.
Web
Address: 2945 W Peterson Ave Ste 103, Chicago, IL 60659, United States
Phone: +1 312-877-6154
IDE is another interesting candidate if you're effectively building a digital product, not just a website. They explicitly build web applications, portals and custom software, and describe their approach as user-centered strategy + design + development. adagetech.comwww.ideinteractive.com

IDE Interactive

Best for: custom member portals, complicated workflows, integrations, dashboards, or eventually turning the portal into a broader digital platform.

4. Nicer Collaborative: A Creative Studio — particularly interesting for arts/culture

Nicer Collaborative: A Creative Studio
Web
Address: 1361 N Ashland Ave Storefront, Chicago, IL 60622, United States
Phone: +1 312-972-4009
This is a smaller Chicago creative studio that combines branding, UX, web development and web applications. Its work appears particularly compatible with arts/culture and event-driven organizations, including workflows involving calendars, ticketing, membership and e-commerce.

Best for: a smaller, hands-on team where the portal needs to feel beautiful and closely integrated with the organization's brand.

5. Sandstorm Design — strong design/accessibility candidate

Sandstorm Design
Web
Address: 4422 N Ravenswood Ave #50, Chicago, IL 60640, United States
Phone: +1 773-348-4200
Sandstorm is a Chicago digital agency with a focus on UX, inclusive design, accessibility and enterprise web development. I'd put them on the list if the portal needs to serve a broad, diverse membership and accessibility is an important requirement.

Best for: UX research, accessibility, content strategy, complex institutional websites.

6. Venture Industries Online — the arts-specific wildcard

This one deserves special attention. Venture Industries Online is explicitly built around arts organizations and artists, rather than simply having nonprofits somewhere in its portfolio. It has worked with the League of Chicago Theatres, and its arts clients include opera companies, theaters, orchestras and museums. ventureindustriesonline.com

It also offers event management, email marketing, CRM integration, custom programming and member/password-protected functionality. ventureindustriesonline.com

Best for: an arts organization that wants an experienced arts-tech partner rather than a general-purpose digital agency.

7. Heller Consulting — if CRM/data is the hard part

Heller Consulting
Web
Address: 53 W Jackson Blvd, Ste 622, Chicago, IL 60604
Phone: +12242417489
I'd consider Heller if the portal is really part of a larger CRM/member-data transformation. They specialize in technology consulting for nonprofits and social-sector organizations, including CRM implementations and Salesforce/Blackbaud ecosystems.

Best for: Salesforce/CRM, data migration, systems architecture, integrations and organizational change—not primarily visual design.

My recommended shortlist

If I were running your procurement process, I'd invite four firms to discovery calls:

I'd add Heller if CRM/data integration is substantial, and Sandstorm if accessibility and UX research are major requirements.

One useful benchmark: Chicago Loop Alliance's recent website/CRM RFP is surprisingly close to the kind of problem you're describing—it called for integrating membership, event registration, fundraising, member billing/payments, member listings, applications, CRM/AMS and the website, rather than treating the portal as an isolated website. loopchicago.com That's the level of systems thinking I'd look for in your agency selection.

One important procurement recommendation

Before approaching agencies, I'd make them respond to the same 2–3 page brief describing:

• current website/CMS
• current membership database/AMS/CRM
• number and types of members
• dues/renewal model
• events/ticketing
• member directory
• gated content/resources
• payments
• email/marketing automation
• staff/admin workflows
• accessibility requirements
• integrations you already have
• what you want members to be able to do after logging in
• approximate budget and desired launch date

Then ask each agency to recommend the technology stack, rather than specifying one yourself. That will expose whether you're actually buying a custom portal—or whether an existing AMS/member platform with a beautifully integrated front end would accomplish the job for substantially less.

If you tell me your approximate membership size, current CRM/membership system, and budget (e.g. $25–50k, $50–100k, $100k+), I can narrow this to 3–5 firms and compare them on arts experience, portal capability, likely budget tier, technology approach, and relevant past projects.

Yes. For a Chicago arts nonprofit, I’d prioritize firms that understand both arts/culture audiences and the unusually tricky combination of membership, events, payments, CRM, and authenticated member experiences.

My shortlist

1. Adage Technologies — strongest technical/custom-portal candidate
   • Chicago-based and substantially more engineering-oriented than a typical creative agency.
   • Particularly interesting if you want a true member portal rather than simply a redesigned website with a membership plug-in.
   • Their nonprofit work includes a self-service “My Account” portal and integrations, which is relevant to your requirements. loopchicago.com
   • I'd approach them if: you need custom workflows, integrations, sophisticated account management, or expect the portal to become a significant digital product.

2. Dialogue Theory — strong UX + mission-driven digital partner
   • Chicago studio focused on digital strategy, UX/UI and web development for mission-driven organizations.
   • I'd put them on the RFP list if the portal needs to feel beautiful, intuitive and aligned with an arts organization's brand, rather than like a generic association-management system.

3. Venture Industries Online — particularly compelling for arts organizations
   • This is the most obvious arts-sector specialist I found.
   • They explicitly work with arts organizations and artists, and cite projects for the League of Chicago Theatres, Lyric Opera, and Racine Theatre Guild. The League of Chicago Theatres testimonial specifically describes a complex overhaul serving member theatres, patrons, artists and administrators. ventureindustriesonline.com
   • I'd definitely include them in the first round.
   • Venture Industries Online

4. Sandstorm Design — excellent if accessibility and UX are priorities
   • Chicago-based, women-led agency with emphasis on UX, inclusive design and enterprise web development.
   • Their experience with data-driven applications and CMS platforms makes them worth considering for a more sophisticated portal.
   • I'd approach them if: accessibility, user research, information architecture and a polished member experience are major priorities.

5. Orbit Media Studios — strong nonprofit + Chicago track record
   • Their nonprofit portfolio includes Goodman Theatre, with a reported 55% increase in conversions, as well as Alliance Theatre and other nonprofits. www.orbitmedia.com
   • Their focus appears somewhat more website/content/strategy-oriented than portal-engineering-oriented, so I'd ask specifically about their experience with authenticated membership systems.
   • Orbit Media Studios

6. View Marketing & Creative — good fit for a smaller/mid-sized organization
   • They have unusually relevant Chicago nonprofit membership experience: they built the website for Chicago Women in Philanthropy and coordinated the integration and styling of its existing membership software. www.view-marketing.com
   • This is a good choice if you don't necessarily need to build the membership engine from scratch and instead want a beautifully branded website + seamless member experience around an existing platform.

One important distinction

I'd first decide whether you actually need a custom membership portal.

There are roughly three approaches:

For an arts nonprofit, the portal might eventually need things like member profiles, renewal/payment, event registration, member-only resources, artist/theatre directories, discounts, committees, newsletters, ticketing integration, CRM synchronization and different permission levels. Chicago organizations are already dealing with this level of complexity—for example, Chicago Loop Alliance's recent technology requirements called for member information, events, payments, donations, QuickBooks integration, CRM synchronization and ADA accessibility. loopchicago.com

If it were my RFP

I'd invite 5 firms to a first conversation:

Adage Technologies · Venture Industries Online · Dialogue Theory · Sandstorm Design · Orbit Media Studios

And I'd use View Marketing as a sixth/benchmark proposal if you're considering an existing membership platform rather than building the whole thing.

I would not start with a generic nonprofit web-design shop just because they have a nice portfolio. A membership portal is fundamentally a product/UX/integration project, and the ability to make a pretty homepage is a different skill.

If you tell me roughly (a) your annual budget, (b) number of members, (c) what the portal needs to do, and (d) what CRM/membership/ticketing system you currently use, I can narrow this to 3 firms and tell you exactly what I would ask each one in the RFP.

Yes. For a Chicago arts nonprofit, I’d build a shortlist around firms that understand both mission-driven digital experiences and the less glamorous parts of membership: member records, renewals, payments, events, permissions, CRM integrations, and staff administration.

My first calls

1. Adage Technologies — strongest choice for a genuinely custom portal
   • Chicago-based software/web development firm with substantial custom application capability.
   • Particularly interesting for you because Clutch specifically highlights Adage’s arts and nonprofit-sector expertise and custom web/application development. clutch.co
   • I’d put them at the top if the portal needs sophisticated member accounts, integrations, complex permissions, or a custom backend.
   • Adage Technologies

2. Sandstorm Design — strongest UX/accessibility-oriented option
   • Chicago agency with deep experience in mission-driven organizations, UX, inclusive design and enterprise web development. clutch.co
   • Good candidate if the portal needs to feel beautiful and arts-oriented, rather than like a generic association-management system.
   • Their technical capabilities include data-driven applications and platforms such as Drupal and WordPress.
   • Sandstorm Design

3. Orbit Media Studios — particularly compelling for an arts/cultural organization
   • This is probably the best "arts nonprofit + website + member experience" conversation I'd have.
   • Orbit has worked with Goodman Theatre and other nonprofits, and specifically discusses custom integrations, event registration, resource libraries, accessibility and UX. Goodman Theatre's testimonial says Orbit helped represent it as a "world-class cultural institution." www.orbitmedia.com
   • They also have a substantial Chicago nonprofit track record. clutch.cowww.orbitmedia.comwww.dialoguetheory.com
   • Orbit Media Studios

4. Dialogue Theory — boutique option I'd seriously consider
   • Smaller Chicago studio focused on complex digital experiences for nonprofits and civic organizations. Their positioning is explicitly about combining strategy, UX, design and technology rather than simply building a website. www.dialoguetheory.com
   • Could be an excellent fit if you want a high-touch, highly customized member experience rather than a big-agency process.
   • Dialogue Theory

5. View Marketing & Creative — worth a conversation if the portal is relatively straightforward
   • They have unusually relevant evidence: their work for Chicago Women in Philanthropy included styling a membership portal to match the organization's Webflow site, with member dashboards and CMS functionality. www.view-marketing.comwww.chicagoculturalalliance.orgloopchicago.com
   • I'd investigate them if you're envisioning something like member login, profile management, directory, events/resources and payments rather than a deeply custom software application.
   • View Marketing & Creative

One important distinction

I'd first determine whether you actually need an agency-built membership portal or whether you need an existing membership/association platform customized and integrated with your website.

For example, Chicago's own membership ecosystem includes organizations using systems such as Neon CRM, and there are platforms that already provide member portals, renewals, events, payments and directories. www.chicagoculturalalliance.org

If your requirements are mostly:

• member login/profile
• membership levels and renewals
• dues/payment processing
• member directory
• event registration
• private resources
• email communications
• staff/admin dashboard

…I would not automatically commission a custom application. You could spend substantially more than necessary.

If instead you need things like:

• complicated membership eligibility
• multiple classes of artists/members
• custom benefits/entitlements
• member-generated content
• artist portfolios
• sophisticated permissions
• integration with ticketing, CRM, accounting or donor systems
• unusual renewal/payment rules
• a highly distinctive cultural-sector UX

…then Adage, Sandstorm, Orbit or Dialogue Theory become much more compelling.

How I'd run the selection

I'd invite 4 firms to respond to the same short RFP:

I'd then ask each one to provide a fixed-price discovery phase, rather than immediately asking for a full build quote. That discovery should produce the recommended platform/architecture, member journey, integrations, data model, accessibility requirements, implementation cost and ongoing maintenance cost.

One particularly useful benchmark: a recent Chicago Loop Alliance RFP described a very similar problem—website plus CRM/association-management functionality, member/donor/event management, communications and payment processing—so your RFP should explicitly cover those areas rather than simply saying "membership portal." loopchicago.com

If you tell me roughly how many members you have, what your current website/CRM/ticketing system is, and what you want members to be able to do inside the portal, I can narrow this to 3 firms and give you a recommended RFP scope and budget range.

Yes. For a Chicago arts nonprofit, I’d prioritize firms that understand both membership/CRM infrastructure and the front-end member experience, rather than hiring a generic web-design shop.

My shortlist

1. Promet Source — strongest choice for a complex portal
   • Chicago-based, with deep nonprofit/association experience.
   • Particularly strong if you need a secure, accessible portal with sophisticated permissions, integrations, content management, and custom workflows.
   • Drupal/WordPress expertise is useful if the portal needs to live alongside an existing institutional website.
   • I’d put them on the RFP list if this is a substantial technology project. loopchicago.com

2. Giant Rabbit — strongest arts/nonprofit specialist
   • This is probably the most directly relevant firm I found. They explicitly specialize in arts & culture organizations and have worked on membership, donation, ecommerce, CRM, and website integrations for museums and other arts organizations.
   • They say they've served 300+ nonprofits and specifically cite integrating membership systems with websites, stores, accounting, events and CRM systems. giantrabbit.comyab.dev
   • Giant Rabbit

3. Yab — best if you need a genuinely custom member portal
   • Their arts/culture practice is unusually specific: they build donor and member portals, integrate with Spektrix and Tessitura, and connect those systems to donor CRMs and websites.
   • Their examples include member self-service, renewals, ticket access, giving history and benefit lookup. yab.dev
   • This would be one of my first calls if you're a performing-arts organization or use Tessitura/Spektrix.
   • Yab

4. Sandstorm Design — best for UX + sophisticated website
   • Chicago agency with a strong UX/design orientation and experience with mission-driven organizations.
   • Worth considering if the portal needs to feel exceptionally polished and accessible, rather than being primarily an administrative/member-management system.

5. Dialogue Theory — good boutique option
   • Chicago-based digital design/development studio focused on mission-driven organizations.
   • I'd consider them for a smaller, more design-led portal where you want senior attention rather than a large agency team.

6. Maven Digital — interesting nonprofit-focused alternative
   • Chicago digital-product consultancy with a nonprofit/social-impact orientation and clients including Shedd Aquarium, Chicago Community Trust and other major mission-driven organizations.
   • Worth an exploratory conversation if the portal involves broader digital-product strategy rather than simply website development.

One important distinction

Before choosing an agency, I'd decide whether you actually need a custom membership portal or a membership platform with a branded front end.

For example, Cuseum has a purpose-built branded member/supporter portal for cultural organizations, including member benefits, account management, digital membership cards and integrations with systems such as Tessitura, Altru, Salesforce and Neon CRM. cuseum.com

Likewise, Neon One is worth evaluating if your underlying problem is really membership + donor CRM + events rather than custom software. It specifically markets an integrated solution for arts/culture organizations and has Chicago arts clients. neonone.com

Who I'd actually invite to the first round

If I were running your procurement, I'd send an RFP to:

Giant Rabbit + Yab + Promet Source + Sandstorm Design

That gives you four quite different approaches:

I'd also ask Cuseum and Neon One for demos—not necessarily as agency bidders, but to establish whether buying/configuring an existing platform could accomplish 70–90% of what you're envisioning for substantially less money.

One useful signal: a recent Chicago Loop Alliance RFP described almost exactly this kind of problem—website + CRM + association/membership management + donor tracking + events + communications + payments—which suggests the local market has relevant experience with this combination. loopchicago.com

If you tell me (1) your approximate membership size, (2) what CRM/ticketing system you use now, (3) what you want members to do inside the portal, and (4) rough budget ($50k / $100k / $250k+), I can narrow this to 3 agencies I'd interview and explain exactly why, including relevant arts clients and comparable projects.
